Theme Park and Associated DevelopmentsFinal Environmental Impact AssessmentFIXED PLANT NOISEFixed Plant Inventory4.2.15 Noise levels from fixed plant sources within the Study Area are required to comply withthe EIAO-TM. The fixed plant noise sources assessed in this EIA include:the Penny's Bay PTI and the temporary PTI at Yam 0 rail station;the Theme Park amusement operations (Phases 1 and II);the sewage pumping station at Penny's Bay;the parking lots proposed at Penny's Bay;CLP's gas turbine power station in Penny's Bay; andthe future Container Terminal development (previous Container Terminals 12 and 13) planned to the south-eastof the Theme Park.Fixed Plant Noise Criteria4.2.16 The EIAO-TM requires that all fixed noise sources be located and/or designed such that:• the total fixed source noise level at the facade of the nearest NSR is at least 5 dB(A) lower than the appropriateANL as specified in the IND-TM (note, these are the same ANLs as shown in Table 4.2c for railway noise);or• where the prevailing pre-Project noise level in the area is 5 dB(A) or more below the appropriate ANL, the totalfixed source noise level must not exceed this pre-Project noise level.4.2.17 The Corrected Noise Levels or CNLs (corrected for the presence of tonality, impulsivenessand intermittency) at the various NSRs due to fixed noise sources are normally developedin accordance with the IND-TM. The noise impacts of the various fixed plant sources areconsidered to be cumulative. Therefore, in assessing the overall noise impact of fixed plantsources, the individual fixed source noise levels at each NSR are combined.4.2.18 Once again, while assigning Area Sensitivity Ratings to the various types of areas whichcould contain NSRs, the IND-TM groups Country Parks together with rural areas andvillages as having the highest inherent sensitivity to intrusive noise. However, CountryParks themselves are not considered identical to other NSRs and furthermore, the EIAO-TM does not provide a specific noise limit for Country Parks. Therefore, this EIAevaluates fixed plant noise levels at Country Parks qualitatively.Public Transport Interchanges (PTIs)4.2.19 Under the NCO* PTIs are regarded as "public places" and as such, there is no statutorynoise standards that may be applied to these facilities. Although the predominant sources ofnoise associated with PTIs are road vehicles, road traffic noise standards are not the mostappropriate criteria since road vehicle movements within PTIs represent a relatively fixednoise source compared with the free-flowing traffic on a normal road or highway. Assuch, due to the nature of the noise source represented by PTIs and the characteristics oftheir noise emissions, the appropriate noise limits specified in the IND-TM, as reference,has been adopted for such facilities.ROAD TRAFFIC NOISEScott Wilson (Hong Kong) Udieassodaticm^ti ERM HongKorig 4-5ShanMand Cox * Wilbur Smith Assodates
